Abstract

Summary

The mining regions of Ukraine have specific hydroecological problems, which are most often associated with the pumping of mine waters of abnormal chemical composition and increased mineralization compared to water in surface water bodies. Its accumulation in ponds and tailings storage facilities causes the formation of hydrochemical anomalies. The situation worsens even more when mine waters are discharged into surface water bodies.

The purpose of the study is to assess the ecological risk of discharge of mine water from the storage pond (Svystunov creek, Kryvbas) into the Inhulets river for 2005–2021. Intermediate calculations of the specific discharges of mine water in the specified period, the background mineralization of water in the Inhulets river nearby Novoselivka village.

It was established that during the time selected for research, the environmental impact from the discharge of mine waters into the river increases. This happens due to the increase in the mineralization of the discharged mine waters (from 33.9 g/dm3 to 42.3 g/dm3) and the supply of mine waters to the river (from 0.9 m3/s to 1.52 m3/s). The proposed options for the disposal of mine waters have been analyzed. The most effective option is their demineralization.
